A First-in-Human, Phase 1a/1b Trial to Assess the Safety, Tolerability and Preliminary Efficacy of LY4175408, an Antibody Drug Conjugate Targeting Protein Tyrosine Kinase 7-Expressing Tumor Cells, in Participants With Selected Advanced Solid Tumors

Status: Recruiting
Location: See all (27) locations...
Intervention Type: Drug
Study Type: Interventional
Study Phase: Phase 1
SUMMARY

The purpose of this study is to measure the safety and efficacy of LY4175408 in participants with selected advanced cancer. In addition, this study will evaluate how much LY4175408 gets into the bloodstream, how it is broken down, and how long it takes the body to get rid of it. Participation could last up to 4 years.

Eligibility
Participation Requirements
Sex: All
Minimum Age: 18
Healthy Volunteers: f
View:

• Have one of the following advanced or metastatic solid tumor cancers:

‣ Non-small cell lung cancer (NSCLC)

⁃ Small cell lung cancer (SCLC)

⁃ Endometrial cancer

⁃ Triple negative breast cancer (TNBC) (characterized by HR-negative disease and HER2-negative expression according to American Society of Clinical Oncology (ASCO) - College of American Pathologists guidelines).

• Received all standard therapies for which the individual was deemed to be an appropriate candidate by the treating investigator (except in Cohort B1 and B2 expansion, which require participants who are treatment naive in the advanced metastatic setting); OR the individual is refusing the remaining most appropriate standard of care treatment; OR there is no standard therapy available for the disease.

• Eastern Cooperative Oncology Group (ECOG) performance status of greater than or equal to (≤) 1.

• For dose optimization/dose and expansion cohorts (Cohort A2, Cohort B/C): Measurable disease per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1.

• Cohorts B1/B2: NSCLC with no known actionable genomic alterations. ≤2 prior lines of systemic therapy for advanced or metastatic disease in safety lead-in; no prior systemic therapy in expansion
